Last time I lived under someone in an apartment, I had a noise issue. I dont think I ever left a note though because I was scared of who lived in the apartment.
It was a couple, and not even one week after they had moved in, I could hear them fighting. After one got done beating on the other (you could hear the screaming and crying), 30 minutes or so later, you would hear the mattress squeaking and the loud moaning. I was perplexed.
This went on for months; they truly seemed crazy to me, always fighting then fukking. Sometimes I'd hear the one crying while the abuser walked around singing gospel very loudly; he was very heavy-footed and his voice would echo all over the apartment.
One day they came out of the apartment, and I saw it was actually two men...who I thought had been a woman screaming all that time was really a man - very petite and cute. The other man was quite large and slovenly. I looked at him and was wondering why these two were a couple in the first place. Lookswise, they didn't seem equally yoked at all, but I digress.
One day, I saw the smaller one land past my patio railing. He had jumped off the second floor patio upstairs to get away from his boyfriend. Early morning, afternoon or nighttime, they didn't care - they kept the antics going.
There was no way in hell I was going to confront these folks, and even if I did, I would not have known what to say. I figured, if the big one would regularly swing on his own boyfriend/ lover, there is no telling what he would do to a woman he didn't know.
